For pressure after measurement filter, and first sensor 4 and second sensor 9 are connect by harness 5 with controller.
Controller can determine that filtering pressure is poor according to pressure after pressure before filtering and filter, i.e., filter 1 is pressed after filtering preceding pressure and filter
The difference of power.In addition, fuel oil when controller prestores corresponding filtering pressure difference limit value, the i.e. life termination of filter 1 poor with filtering pressure
The maximum value of flow resistance namely the fuel oil flow resistance of the filter 1.During the work time, controller is by the measurement knot of pressure sensor
Fruit and the filtering pressure difference limit value prestored are compared, and then determine service life situation, it is intuitive for, if the nearly filtering pressure of filtering pressure differential is poor
Limit value, then it represents that filter 1 is needed replacing close to lifetime limitation, filter；If the two difference is more, illustrate filter 1 also
It can continue to use without being replaced.
It is worth noting that, in product design process, the limit value of filter can by one or more to the longevity
The dirty filter of the life limit carries out testing experiment and specifically determines.The filtering pressure difference limit value that controller prestores may be a fixed value,
May also be to have the fitting function of functional relation with pressure before filter, i.e. the maximum value of fuel oil flow resistance is a functional value, although
Specific value will appear variation, but each numerical value can reflect the feature of the filter life limit.When the filtering pressure difference limit value prestored
When for fitting function, controller brings the numerical value of pressure before collected filter to fitting function into can determine that current filtering pressure difference is right
The filtering pressure difference limit value answered.
It should be understood that controller can specifically use programmable logic controller (PLC), as needed equipped with corresponding
The components such as conversion circuit, logic control element, memory, it is performed make difference or compare or prestore the programs such as limit value needed for electricity
